___________________________________________/ Chapter 1 INTRODUCTION
REBEL 3.0 is a spreadsheet that is designed for a diverse mix of
scientific and non-scientific users. It can be tailored to fit the
needs of almost any industry or profession by adding custom 'script'
libraries to its already powerful set of built-in functions. Scripts,
unlike the familiar 'macro', look and behave like built-in functions
and can range from simple conversion routines to full blown
applications. They are easy to write (using a structured C-like
programming language) and are accessed from separate library files,
making them easy to share with others. REBEL's features do not end
with scripts, however. Its built-in Coordinate Geometry and Matrix
Algebra packages offer computing power that is unmatched by any other
spreadsheet. The 27 functions that comprise these packages allow
spatial data, as well as matrixes, to be manipulated with the same
event driven (what-if) engine that is used for standard functions.
Simply put, no other spreadsheet can match REBEL's flexibility and
power.
As you read through this manual, you'll find that REBEL has not
hesitated to break with tradition in its effort to develop the most
sophisticated spreadsheet you'll ever use. Listed below are a few
additional examples of what make this spreadsheet so unique.
CELL ADDRESSES
While most spreadsheets on the market today use letters
to refer to the columns of other cells, REBEL uses
numbers (e.g. 'AB12' would be equivalent to [12,28] in
REBEL - row 12 column 28).
INDIRECT CELL ADDRESSING
The ROW and/or COLUMN fields of a Cell Address can
themselves be expressions, allowing Cell Addresses to
be nested. This means that a cell reference can vary,
depending on the values of other cells (very handy for
table lookups).
[ROW, [row,column] ]
\__________\
\__ The value from this
cell will be used as
COLUMN number
ARRAYS
Upto 8000 values (array elements) can be assigned to each
cell! Each of these values can be accessed by including
the optional 3rd Array Element field in the Cell Address:
[row,column,ELEMENT]
MULTIPLE WORKSHEETS
Upto 4 separate worksheets can be loaded at one time.
Cells from any of these worksheets can be individually
addressed by including the optional 4th Worksheet Level
field in Cell Address:
[row,column,element,WORKSHEET]
NOTE: Both the 'Array Element' and 'Worksheet' fields of
a Cell Address are optional. Their values default to
zero if not included.
OVER THIRTY (30+) OPERATORS:
Unary ! + -
Arithmetic ** * / % + -
Relational > >= <= < == !=
Logical && ||
Bitwise << >> & |
Ternary ?:;
Assignment = += -= *= /= %= <<= >>= &= |=
PROGRAMMABLE RANGE OPERATIONS
A 'Range Operation' can be defined that temporarily
assigns one or more 'formulas' to a group of cells,
returning a single value upon completion. The general
form of a Range Operation is similar to that of a
standard Cell Address and can be used within other
formulas in much the same manner.
REBEL does not stop here, however. Every effort has been made to make
this the simplest spreadsheet you have ever used. Function keys are
designed to act like built in macros that perform complex editing
tasks, which you would otherwise be forced to develop yourself.

________________________________________/ Chapter 2 GETTING STARTED
When REBEL is first invoked, you will be presented with an empty
worksheet at the 'Root Menu Level'. Each cell can have either a
'label' (text string) or a 'formula' associated with it. Formulas
consist of numbers or expressions that may or may not be based on the
results of other cells.
The screen is divided into three regions: 1) the "Function Key Menu"
at the top; 2) the "Input Line" for entering text or formulas; and
3) the "Cells" that comprise the worksheet. The options, displayed
by the Function Key Menus, if written entirely in upper case letters,
will re-assign a new set of options to each function key; or, if they
are abbreviated in both upper and lower case letters, they will perform
a specific action. The first menu you will encounter upon entering
the spreadsheet is referred to as the "Root Menu".

|5| (active cell)
|6|
:
[2,3]+10 <-- (formula of active cell)
Two cursors are displayed on the screen. The large highlighted area on
the worksheet is referred to as the "Cell Pointer". It points to the
currently active cell that is about to accept a new or modified entry.
This cursor (or pointer) can be moved at any time with arrow keys on
your keyboard. The second, smaller cursor is located on the "Input
Line" (just below the Function Key Menu). It is used to enter a text
or formulas into the cell highlighted by the Cell Pointer.
The remaining portion of this section will provide you with a quick
overview of some of the basics you will need to get started. You'll
learn how to start REBEL, how to move between worksheet levels, how to
use the Function Key Menus, and how to enter data. For more details
on each of these topics, refer to the Technical Information section
in Chapter 6.
GETTING STARTED
______________________________________________________________________
|
|
Starting | If you will be starting this program from a floppy
from floppy | disk (assumed to be in drive A), type the following
drive | sequence of commands from your computer's system
| prompt:
|
| A: (moves you to Drive A)
| CD \ (change to root directory)
|
| REBEL (for color mode)
| or
| REBEL -b (for black and white mode)
|
|
Installing | To permanently install REBEL on your hard drive (assumed
REBEL on a | to be Drive C), you need only copy the .EXE and .DOC
Hard Disk | files from the floppy disk. The following series of
| commands is but one example of how to do this:
|
| C: (moves you to Drive C)
| CD \DOS (change to a subdirectory
| called: 'DOS' if it exists)
|
| COPY A:*.EXE *.*
| COPY A:*.DOC *.*
|
| (If you create a separate subdirectory for the REBEL
| .EXE and .DOC files, be sure to include it in your
| search path; otherwise, you'll need to move to THAT
| directory to execute the program.)
|
|
Root Menu | A variety of operations can be performed using the
| function keys on your keyboard. The specific task
| assigned to each of these keys can vary, however,
| depending on the menu displayed at the top of your
| screen. The first menu that appears when you startup
| the program is called the 'Root Menu'.
| _______ _______ _______ _______
| | f1 | | f2 | | f3 | | f0 |
| | CELL | | EDIT | | FILE | . . . | EXIT |
|
| This menu is used (as a starting point) to re-assign
| a new set of options to the function keys. Notice that
| the descriptive words are written in UPPER CASE
| letters.
|
|
Return to | In most menus, the F1 function key (DONE) will return
Root Menu | you to the Root Menu.
|
|
Exiting | You can terminate your session by pressing the F10
| function key (EXIT) from the "Root Menu".
|
|
Moving the | You can move the Cell Pointer from cell to cell with
Cell | the Arrow Keys or jump from screen to screen with the
Pointer | following keys:
|
| <Pg Up> moves Cell Pointer UP one screen.
| <Pg Dn> moves Cell Pointer DOWN one screen.
| <Home> moves Cell Pointer LEFT one screen.
| <End> moves Cell Pointer RIGHT one screen.
|
| NOTE: You can not move the Cell Pointer with the arrow
| keys once you have started an entry.
|
|
Entering | All cell entries are made from the Input Line (above
Formulas | the Column Bar). A special 'Edit Mode' is also
and Labels | available to modify existing entries (refer to
| Chapter 5).
|
|
Referencing | The value of any cell within the spreadsheet can be
values in | used in another cell's formula by surrounding the
other cells | ROW and COLUMN number (of the cell that contains
| the value) with square brackets []. This is called
| a "Cell Address".
|
| [row,column]
|
| Example: If you want to multiply the value in
| cell [1,2] (row 1, column 2) by 5 and display
| the answer at your current cell location, the
| formula might look something like this:
|
| [1,2] * 5
|
| IMPORTANT! When entering values, never being a
| number with a zero (unless, of course, the number
| is zero). That is, if you want to enter "45",
| don't type it as "045" (if you do, you'll get the
| decimal equivalent of OCTAL 45). Refer to Section
| 6:13 - Misc Topics, for an expanded discussion.
|
|
Cell Types | A cell takes on one of three possible cell types
| (FORMULA, LABEL, or VARIABLE LABELS) whenever you
| enter data. The spreadsheet will automatically try
| to choose the correct cell type for you; and, in
| most cases, it will do it correctly. There are,
| however, a few cases that can confuse the spreadsheet;
| so, it is worth a brief look to see exactly how an
| entry is interpreted.
|
| FORMULA A FORMULA cell type is assigned to a
| cell whenever a number, expression, or
| function is entered. For example:
|
| 1.00 (number)
| [1,2]+200 (expression)
| +sqrt(16) (function)
|
| Any entry that begins with one of the
| following characters:
|
| + - ( [ . 0 1 2 3 4 5 6 7 8 9 @
|
| will be automatically be interpreted as a
| mathematical 'formula' and the spreadsheet
| will attempt to compute its value. It is
| important, however, to remember that some
| valid formulas may NOT begin with one of
| these characters. In these cases, you must
| begin the entry with a Plus (+) sign to
| FORCE the spreadsheet to interpret it
| as FORMULA.
|
|
| LABELS A LABEL cell type is assigned whenever
| a string of characters is entered that
| DOES NOT BEGIN with one of the characters
| that defines a FORMULA cell. The entry
| will be displayed exactly as it is typed
| and the spreadsheet will attach no special
| meaning to it. For example:
|
| January the 1st
|
| Note: If a LABEL must begin with one of
| the characters that defines an FORMULA, a
| Single Quote (') can be used force the
| spreadsheet to interpret it as a LABEL.
| The optional single quote ('), at the
| beginning of the entry, will not appear
| when the LABEL is displayed. For example:
|
| '1st of January
|
|
| VARIABLE The VARIABLE LABEL is a special type of
| LABEL LABEL cell that is treated a little
| different by the spreadsheet. These entries
| MUST begin with a Double Quote ("). They
| are normally displayed as they are entered,
| except when a Cell Address (e.g. "[1,2]")
| is encountered within the string. In this
| case, the Cell Address is replaced by the
| 'contents' of the cell being referenced.
|
| Example: If the cell at [1,1] (row 1,
| column 1) contains the label: 'red
| and you then make the following entry
| at cell [3,1]:
|
| "My car is [1,1].
|
| it will actually display:
|
| My car is red.
|
| Note: The Double Quote (") IS REQUIRED to
| force [1,1] to be replaced by the contents
| of that cell. If you tried this, type
| something else in cell [1,1] and see what
| happens!
|
|
Attaching | REBEL now allows you to access functions (i.e. scripts)
Scripts | from special (.REB) library files. The documentation
LibrariesB | for these libraries is usually contained in a (.DOC)
| file of the same name. Before you can access these
| scripts, however, you must first 'attach' the library
| contains them. For example, to access the scripts in
| REBEL's standard library, STDLIB.REB, simply start the
| program using the -L: option (followed immediately by
| the name of the library).
|
| REBEL -L:STDLIB
|
| Refer to Chapter 11 for more details on the use of
| scripts.
|
|
Using the | You can move the Cell Pointer directly to any cell on
(/) GOTO | worksheet, without using the arrow keys. This can be
Command | very handy if you need to move the Cell Pointer a long
| distance or to another worksheet at a different level.
| To do this, simply type a slash (/) at the Input Line
| (located above the Column Bar). You will then be asked
| to enter the Row, Column, and Worksheet Level of the
| cell you wish to move to. You can press the <Enter>
| key at any of the prompts to accept the default value
| that is enclosed within the square brackets [].
|
|
Escaping | If you do not wish to complete an option that is
from a | prompting you for information, press the <Esc> key
Prompt | to abort. You will be returned to the Input Line.

_________________________
___________________________________________/ Chapter 3 TUTORIAL
In the following tutorial, you will design a simple spreadsheet that
can be used to compute your monthly car or mortgage loan payment.
It should end up looking something like this:
_________________________________________
Loan size: 10000.00
Annual Interest Rate: 0.12
Length of Loan (years): 3.00
Monthly Payment: 332.14
_________________________________________
IMPORTANT: In the exercise, you will be using the 'PMT' script which
is contained in the STDLIB.REB library file. It is, therefore,
necessary to 'attach' this library before beginning this tutorial. To
do this, simply exit the program and restart it with the following -L
option at the DOS prompt:
REBEL -L:STDLIB
NOTE: If you make a mistake or you wish to change a value while
performing this exercise, simply move the Cell Pointer back to the
cell and re-type the correct entry.
MAKE SURE YOU'RE ON THE RIGHT CELL BEFORE YOU START TYPING!
______________________________________________________________________
|
Step 1 | Using the arrow keys, move the Cell Pointer to cell
| [3,2] (row 3, column 2)
|
Step 2 | Type "Loan size:" (without the quotes)
|
Step 3 | Move right to cell [3,5]
|
Step 4 | Type: "10000" (without the quotes)
|
Step 5 | Move down and to the left to cell [4,2]
|
Step 6 | Type: "Annual Interest Rate:" (without the quotes)
|
Step 7 | Move right to cell [4,5]
|
Step 8 | Type: ".12" (without the quotes)
|
Step 9 | Move down and to the left to cell [5,2]
|
Step 10 | Type: "Length of Loan (years):" (without the quotes)
|
Step 11 | Move right to cell [5,5]
|
Step 12 | Type: "3" (without the quotes)
|
Step 13 | Move down and to the left to cell [7,3]
|
Step 14 | Type: "Monthly Payment:" (without the quotes)
|
Step 15 | Move right to to cell [7,5]
|
Step 16 | Type: "+PMT([3,5],[4,5]/12,[5,5]*12)" (no quotes)
|
| (Notice the plus sign in front of the function call.)
If you got "332.14" for the payment, congratulations, you entered
everything right! Now, you can compute any payment you like, simply
by re-entering the appropriate values in cells [3,5] thru [5,5].
The next steps describe how to save this worksheet.
|
Step 17 | From the ROOT MENU, press function key F3 (FILE)
|
| You should now see a new set of options displayed
| on the "Function Key Menu". These options are
| used to SAVE and LOAD (retrieve) worksheets.
|
Step 18 | Press function key F4 (Save).
|
| You should now see a prompt, requesting the name of
| the file to store this worksheet in.
|
Step 19 | At the prompt, enter: "PAYMENTS" (without the quotes)
|
| If you did everything correctly, your worksheet
| should be been saved in a disk file called.
| PAYMENTS. You can reload it at any time with the
| F3 (Load) option.
|
________________________________
_____________________________________/ Chapter 4 FUNCTION KEY MENUS
The Function Key Menus that appear at the top of your screen are
composed of two types of options. Those that:
1) perform specific operations or commands
2) and those that display a new Function Key Menu.
The word in the descriptive box that identifies each of these options
will help you determine how it is used. For example, a function key
that loads a new set of menu options will always be written in UPPER
CASE LETTERS; while function keys that perform commands, will always
be written in BOTH UPPER AND LOWER CASE LETTERS.
Occasionally, when you press a function key, a prompt will appear
requesting additional information. These prompts have a specific
format that's worth learning:
Question... (options)? [default]: _
| |
the range of legal _______| |____ the default answer
answers are displayed that will be used
within parentheses if only the <Enter>
key is pressed
Important! If, for any reason, you should need to abort an option
without completing it, simply press the <Esc> key. You will be returned
to the Input Line and no further action will be taken.
Note: Some prompts will request that you move the Cell Pointer to
another location with the arrow keys (e.g. when you need to define the
lower right hand corner of a range of cells). Normally, the arrow keys
work fine for this - except when you need to move long distances. In
these situations, the Forward Slash (/) "Goto" Command can be used at
the prompt to initiate a jump to another worksheet location (refer
to Chapter 7).
The remainder of this section describes each of the Function Key Menus
in detail. Most options are non-destructive, with the exception of
the Clear, Purge, and Delete options; so, don't be afraid to try them.
Remember, the <Esc> key will break you out of almost anything.

The F7, F8, and F9 keys do not perform any action other than to
set up the option.
f7 Purge: Removes one or more cells, freeing the memory for
other uses.
Shift: Moves one or more cells one cell position up, down,
left, or right. This command will only shift
OCCUPIED cells that are ADJACENT to the Cell
Pointer. As a result, the position of the Cell
Pointer is important, as it can influence which
cells are actually shifted. Take the following
example. If you want to shift a 'column' of cells
UP, LEFT, or to the RIGHT, you must place the Cell
Pointer on the last occupied cell in the column
that you wish to be included. This would be the
cell with the 'highest' row number in its Cell
Address. The cells that will be shifted will
include everything above the Cell Pointer until
the first empty cell is encountered. When shifting
a 'column' of cells DOWN, place the Cell Pointer at
the top of the column (the cell with the 'lowest'
row number in its address). Everything below this
point will be shifted until the first empty cell is
encountered.
Move: Moves one or more cells to a new location, anywhere
on the worksheet.
Copy: Copies one or more cells to a new location. The F9
function key is used to set the 'type' of cell copy
that is to take place - relative (rel), absolute
(abs), or value (val).
- Relative (rel) copy means that when you copy
a cell's formula from one location to another,
the 'direct' Cell Addresses within the formula
of the new cell will be adjusted (see Section
6:8 - Direct Cell Addresses). That is, the
'direct' Cell Addresses in the new cell will be
modified to reference cells that are the same
relative distance away from the new cell as they
were from the original cell.
- Absolute (abs) copy means that when you copy
a cell's formula from one location to another,
the Cell Addresses (within that formula) will
not be adjusted. They will reference the same
cells as the original cells do.
- Value (val) copy means that only values (not the
formulas associated with them) are copied. When
using the (val) option to copy the contents of a
POINT, SEGMENT, POLYGON, or MATRIX to another
location, the results will be place into a
'NULL' POINT, SEGMENT, POLYGON, or MATRIX
(refer to Sections 9:6 and 10:7 for an expanded
discussion).
NOTE: Cells can be COPIED or MOVED from one worksheet
level to another with the aide of the Forward Slash
(/) 'Goto' Command discussed in Chapter 7. To do
it, simply type a slash (/) instead of using the
arrow keys from the prompt, requesting you to move
the Cell Pointer the the TARGET cell location. This
will produce a new series of prompts that will allow
you to jump to any Row, Column, or WORKSHEET LEVEL.
Insert: Adds a new Row or Column (depending on the setting
of function key F8) above the Cell Pointer's
current position.
Delete: Deletes the Row or Column (depending on the setting
of function key F8) that currently contains the
Cell Pointer.
f8 Defines the range of cells that will be affected by the F7
setting.
f9 The option associated with this key will only appear when
either the 'Shift' or 'Copy' command have been set with the
F7 function key. Otherwise, the function of this key is
disabled and nothing will appear in its display.
Left, Right, Up, Down: These options only become available
when the F7 'Shift' command has
been set. They establish the
direction the cell(s) will be moved.
(rel), (abs), (val): These choices only become available
when the F7 'Copy' Command has been
set. They establish the 'type' of
cell copy that will take place - a
Relative, Absolute, or Value cell
copy. (Refer back to the discussion
on the F7 'copy' option.)
f0 Executes the user defined option setup by the F7, F8, and F9
function keys.

_______ _______ _______ _______ _______
| f1 | | f2 | | f3 | | f4 | | f5 |
| DONE | |Report>| | Load< | | Save> | | Text< | . . .
f1 - Returns you to the Root Menu.
f2 - Copies a worksheet to a standard text file located in
your current working directory. The report will appear
exactly as it does on your screen. You can then use the
DOS 'PRINT' command to sent the file to your printer.
The report will begin with the first row that appears on
your screen and will continue to whatever row you specify
or until no further data is found - whichever comes
first. You may also set the maximum number of characters
per line (upto 132) or use the default setting that
limits the report to the cell visible on the screen.
f3 - LOADS (opens) a worksheet file, located in the current
working directory, that has been saved using REBEL's
native ".RB2" format. Simply type in the name of the
file that contains your worksheet and press <Enter>. It
is not necessary to include the .RB2 extension. You can
also review all of the worksheets that are currently
available by pressing any of the <Arrow> keys - PRIOR TO
ENTERING A FILE NAME. Each time you do this, one of the
files that has a ".RB2" extension will be displayed
within the prompt's square brackets []. When the file you
are interested in appears, press the <Enter> key to load
it. The tilde (~) wildcard character can be used to
create a pattern that will reduce the number of files you
must to search through. For example, "test~" would
locate: test01, testA, test12, etc.. To use this feature,
however, you must remember to enter the pattern BEFORE
the first arrow key is pressed. That is, once an arrow
key is pressed - the pattern is set. If you press an
arrow key before entering a pattern, the default pattern
will be used (i.e. "~.RB2" which is all of the .RB2
files in the current working directory!). You may want to
experiment with this option to see how it works.
f4 - SAVES (closes) the currently active worksheet to a disk
file, using REBEL's native ".RB2" format. It is not
necessary to include the .RB2 extension when you enter
the file name.
f5 - Opens a TEXT FILE and loads it into the currently active
worksheet, starting at the cell highlighted by the Cell
Pointer. Each 'word' or 'number' within the text file
will be loaded into an individual cell and will be
'typed' as a LABEL. Groups of words can be directed to a
single cell by enclosing the string within double quotes
("..."). Existing data, within the worksheet, will not
be overwritten.
Text files can also be used to load the ARRAY SPACE of a
cell. To do this, the cell must either be empty or
contain an expression (i.e. be a FORMULA cell). A
"HEADER LINE", that describes 'what' and 'where' to
start loading the array, MUST precede the values to be
loaded. The HEADER must begin with a tilde (~) and end
with a semicolon (;). The exact format is defined as
follows:
~[Row,Column,MaxArraySize,Worksheet],START,END;
The following 5 line file, for example, will cause an
Array Space (containing 15 elements) to be defined for
the cell at [55,66]. It will then load 4 values (25.0
thru 28.0), starting at array position 8 and ending at
array position 12.
~[55,66,15,1],8,12;
25.0
26.0
27.0
28.0
The important thing to remember is that the number in the
ARRAY ELEMENT position of the HEADER LINE will define or
re-define a cell's array Area Space - prior to loading
it! Also note that the 'start' and 'end' values, which
follows the HEADER's cell address, define the exact array
positions to be loaded (8 thru 12). More than one such
header entries may be included in a file.
In addition to fixed numbers, expressions that access
values in other cells throughout the worksheet, can also
be used to load the array space. Take the following
example. Here, 4 values (from another worksheet level)
are added to a fixed number and then loaded into the
array elements 8 through 12.
~[55,66,12,1],8,12
25.0 + [1,1,,2]
26.0 + [1,2,,2]
27.0 + [1,3,,2]
28.0 + [1,4,,2]

f8 - LISTS the files in the Current Working Directory. You
can control the number of files that will be displayed
by using the tilde (~) wildcard character to form a
specific pattern. The default pattern (~.~) will
display all files. Press the <Enter> key to accept
the default or enter your own pattern.
f9 - CHANGES the Current Working Directory.
f0 - CLEARS the currently active worksheet.

Section 4:5 SCRIPTS
-----------------------------------------------------------------------
The following menu options allow you to 'attach' Script Libraries,
view the Script Index, adjust the size of the Swap Area, and
assign scripts to function keys - all without exiting the program.
Chapter 11 contains a detailed discussion of each of these topics.

f4 - Allows you to assign a SCRIPT (containing an empty
argument list) to a function key that can be accessed
from the (f5) FKEYS menu. This option will prompt
you for the function key number and the name of the
script. Note: Function key f1 is reserved for the
DONE option and can not be used.
f5 - Accesses a menu of USER DEFINED function keys that
may have scripts assigned to them (see f4 above).

f7 - Used to view summary information about each script
that is contained in the Script Index.
- The SIZE of the script in bytes
- Whether script is loaded in Swap Area
- The NAME of the script's library
- The Library's Version Number
- Version of BUILD.EXE used to create library
- Version of REBEL required to run script
A maximum of 64 entries can be made in this index. The
<Esc> key can be used to exit this option at any time.
f8 - Attaches a (.REB) Script Library to the current
spreadsheet session by loading certain header
information about each script into a special Script
Index. Note, only the scripts contained in this
index can be accessed by the worksheet. (Also see
the -L option discussed in Section 11:2).
f9 - Clears the Script Index, allowing you to 'attach' a
new set of script libraries (see f7 and f8).
f0 - Allows you to increase or decrease the size of the
Swap Area, which is used by the Script Manager to
execute the scripts listed in the Script Index. The
Swap Area must be at least as large as the biggest
script that will be accessed by the worksheet. You
can check the size the the present Swap Area by
selecting this option and then pressing <Enter>. The
size of the Swap Area is dislayed within the square
brackets []. (Also see the -M option discussed in
Chapter 11).

that contains the Cell Pointer). The last window can
not be removed.
f3 - Creates a Horizontal Window, beginning at the Cell
Pointer's position.
f4 - Moves the Cell Pointer to the Next Window - if one
exists. (See the <Tab> Command in Chapter 7 for a
faster way of doing this.)
f5 - Creates a Vertical Window, beginning at the Cell
Pointer's position.
f6 - Changes the CELL WIDTH of the current column. You will
also be asked to enter the number of the last column you
wish this change to affect. Any change made by this
option will override the default column setting (see
Section 4:8 - dWidth).
f7 - Allows you to change the Worksheet LEVEL of the current
window. (The level of each window is displayed in the
extreme left hand corner of the Column Bar - surrounded
by angle brackets <>.).
f8 - Moves the Cell Pointer to the next Margin - to the left
of it's current position (see function key F9).
f9 - Sets or Removes a MARGIN in the column occupied by the
Cell Pointer. Once the Cell Pointer is move off this
column, it can no longer be crossed using the arrow
keys. (A margin can be crossed with the PgUp, PgDn,
End, and Home keys or with the "/" Goto Command
discussed in Chapter 7).
f0 - Moves the Cell Pointer to the next Margin - to the right
of it's current position (see function key F9).
-----------------------------------------------------------------------
Section 4:7 UTILITY
-----------------------------------------------------------------------
IMPORTANT: Function keys F2 thru F6 are used to display the
points, lines, and polygons created by the Coordinate Geometry
Package described in Chapter 9. To provide compatibility with as
many PCs as possible, REBEL uses video BIOS calls for all of its
graphics displays. While this approach extends graphic
capabilities to a wide range of IBM-PCs and compatibles, it does
not always take full advantage of your system's video adapter.
For example, a maximum of three colors can be displayed at a time.

f1 - Returns you to the Root Menu.
f2 - This key is used to set the Graphics Video Mode used by
your PC's ROM BIOS functions. Three modes are
available: 1) Low Resolution Color; 2) Low Resolution
Black and White; and 3) High Resolution Black and White.
f4 - This key is used to set the Video Aspect Ratio, which is
used by the plotting routines to eliminate distortion. It
is not absolutely necessary that it be set unless it is
important that the dimensions of the figures you plot are
proportional. The ratio is formed by the screen's
horizontal and vertical dimensions. Since these
dimensions can differ from system to system, this ratio
must be set to correct for distortion. After measuring
the HORIZONTAL and VERTICAL dimensions of your screen
(using any unit of measure: inches, centimeters, etc..),
simply press this function key and enter the values at
the appropriate prompt.
f6 - This function key is used to plot individual or multiple
POINTS, SEGMENTS, and POLYGONS created by the Coordinate
Geometry (COGO) Package described in Chapter 9. To plot
the coordinates defined by one of these cell types, move
the Cell Pointer to the cell in question and press F6.
You can continue to identify other POINTS, SEGMENTS and
POLYGONS in this same fashion until you press <Enter>,
at which time everything will be displayed. You can exit
from the graphics mode by pressing any key.
